FREDERICE SCHNEIDER, OF VELVA, NORTH DAKOTA.

WRENCH.

To all whom it may concern:

Be it known that I, FREDERICE SCHNEIDER, a declared citizen of theUnited States, residing at Velva I). O., in the county of Mc- Henry andState of North Dakota, have invented new and useful Improvements inIVrenches, of which the following is a specication.

The invention relates to an improvement in wrenches, being moreparticularlyv directed to a wrench construction in which the jaws willreadily accommodate themselves to articles of various sizes. l

The main object of the present invention is the provision of a wrench inwhich the sliding jaw is operated with relation to the fixed jaw by thehandle, so that in the movement of the handle in one direction thesliding jaw is moved toward the fixed jaw to operate with the articlewhile in the movement of the handle in the opposite direction the handleis moved to release the article.

The invention in its preferred details of construction will be describedin the following specification, reference being had particularly to theaccompanying drawing, in which:--

Figure 1 is a view in elevation of the improved wrench. Fig. 2 is asection on the line 2 2 of Fig. 1. Fig. 3 is a vertical section, partlyin elevation, of the wrench, the handle being broken off. Fig. 4L is aperspective view of the movable jaw.

Referring particularly to the accompanying drawing wherein are shown thepreferred details of construction of the improved wrench, 1 denotes thewrench body formed to provide spaced parallel plates 2 and 3,approximately of semicircular shape in elevation and connected at oneend of the diametrical edges by a projection 4L which will behereinafter termed the fixed jaw. This jaw is o-f a thicknesscorresponding to the maximum distance between the relatively outersurfaces of the plates 2 and 3, and its inner edge, which forms theoperative face of the jaw, projects at right angles to the upper planeedges of the plates. The relatively inner surfaces of the plates,throughout their maximum dimensions and in alinement with their upperedges, are formed with grooves 5, for a purpose which will presentlyappear.

The movable jaw comprises a member including a jaw proper 6,corresponding in size and shape with the xed jaw, which Specification ofLetters Patent.

Serial No. 525,434.

jaw 6 is secured upon or integral with a guide bar 7 underlying the jawG and having a length corresponding to the maximum dimensions of theplates 2 and 3. The guide bar 7 is of cruciform shape in cross section,the side ribs 8 of which are designed to be guided lin the grooves 5 ofthe plates 2 and 3, and an upright 9, slidably fitting between thegrooves, will be plain from Fig. 2.

A handle 10 is pivotally connected at 11 to the body 1, said point ofconnection being central of the body at the lowest point thereof. Theupper end of the handle, which rests between the plates 2 and 3 of thebody, is formed to provide a rounded head 12 designed to engage arounded aperture 13 formed in the guide bar 7 of the movable jaw. Bymoving the handle on its pivot it will be obvious that the movable jawmay be adjusted toward and from the fixed jaw as desired, the guide barduring such adjustment moving transversely of the body, as will be plainfrom Fig. 3.

The spaces between the plates 2 and 3 of the body between the guide baropening and the handle opening are preferably closed, the curved edgeson one side being united by an integral strip 14:, and on the other sideby a spring plate 15 fixed at the lower end and free or movable at theupper end. The upper end of the spring terminates immediately beneaththe lower edge of the guide bar when the latter is in position, and thespring serves to permit the movement of the handle so as to carry theupper end thereof wholly beyond the plane of the guide bar, to permitthe complete removal of the movable jaw when desired. In this movementof the handle the upper end displaces the free end of the spring, as isnecessary owing to the relative sizes of the parts, and upon therestoration of the parts to normal position, the spring plate againcloses the opening.

It is, of course, to be understood that while the invention isillustrated as a nut wrench it is equally advantageous as a pipe wrenchor a pipe cutter, in which, in different instances, the respective jaws4: and 6 are to be appropriately formed. Therefore I contemplate the useof any type of jaw which may be necessary or suggested by the particularwork in hand.

It will be obvious that by moving the handle in one direction themovable jaw will be caused to approach the fixed jaw, clamping anydesired object therebetween,Y the reverse movement of the handleseparating the jaws to release the object.

Having thus described the invention, what j spaced plates, a jaw formedintegrally with the body and projectingy above the plates, amovable jawincluding a jaw proper and a guide bar of cruciorm shape,r said platesbeing formed with grooves to receive the guide bar, and a handlepivotaflly mounted between the plates and terminally engaging the notchin the guide barn 2.

In testimony whereof I atlix my signature inpresence ofV two witnesses.
